Speciicationrforming part of Letters Patent No. 17?.,796`.I dated February 22, 1876; application filed October 30, 1875.

To all whom 'it mag/concern Beit known that I, JAMES P. KENYON, ofE

the city of Brooklyn, county otKings and State of New York,have invented a newand;

tion of my hydrant,themovable parts being all down and the water liowing; and Fig. 2`

presents a face view ot" the yoke Y, which binds the bedpiece B to the stock S, as clearly shown in Fig. l.

The principal objects of my invention have been---while retaining familiar parts and easy manual operations-to prevent that destructive shock, or water-hammer, tol which all hydrants with an automatic reaction or seit'- closing provision have been subject, -and to secure theutmost possible exemption from the necessity of digging t'or repairs. The devices contributive to these ends are to be seen in the cylinder G, plunger P, regulator R, and yoke Y; C being punctured fora Wasteway at w, a relief-vent at r, an auxiliary closing device'or relief-vent at a, with triangular ports `at p p; `P being hollow with openings o o at its sides, and two cups, c c', while R has an inverted cup, c, and through the lower part of its stem achannel, d, called the closing duct. Y is designed to obviate a great trouble-the separation of tho bed-piece aud stock, through the pullL on the latter infrosty weather.

of a strong and economical combination ot' parts in the head of the hydrant, dispensing with nuts and bolts and much fitting and finishing. v

To enable those skilled in such work to make a hydrant with my improvements, the following description is given:

S is the stock or body of the hydrant, ot Wood or iron, or partly ot' each, and of suflicient length to place its lower end belowthe reach ot' frost-say, from tive to seven feetaccording to latitude or exposure. Not much less or more than two feet should be left above the ground. The bore should be two inches in diameter, and slots are to be out, as shown .ati I,`,for the accommodationy of H and N. `D is the dome orv cap, formed as shown, the

rim being extended downward over N, and

ately back of the spur *L At that point it is provided with lateral projections, (indicated by the curved line,) which span the nozzleslot and rest in the stock. The drawing shows clearly how all aberrant motion'is prevented. N is the nozzle or spout, provided with tins i i', to cover the front slot t, while its inner vertical end is so formed as to close the slot i when the parts are up the upper projection l| is hollowed at its top, and H rounded over it to prevent friction and favor a rectilinear stroke. T is the tube, which extends from N to the plunger P. It is connected with the former by a thread, and with the latter bya union, u, as shown. G, the cylinder, is suspended in a collar of white or other metal, with an external thread, by which it is inserted in B, as shown. B is the bed'epiece, carrying U at its central part, and attached toS by screws, indicated at s, Fig. 1. Y is the yoke, embracing the coupling end of B, and screwed to S, as clearly shown in Fig. l, with the object already mentioned. The upper cup c is tightened between u and P, c between P and R, and c by theV nut n, in a manner so plainly shown in the drawingas to render a verbal description unnecessary.

The relief-vent r allows the water to recede before the descending cup o', after the latter has reached the bottom of the ports p p. This device will be needed wshether `its apparent equivalent, the auxiliary puncture a, be used or not, as the latter (on every account) must be so small as to greatly hinder the opening stroke in the absence ot' r. The puncture a, however, will probably not always be used, but only in connection with impure or Weedy water, which makes the relietvent essential for its ostensible service. The duct d must be regarded as equally essential as a closing device, notwithstanding the apparent equivaf lency of a, as, in case ot' choking, it can be withdrawn and cleared without digging.

As the hydrant is represented in Fig. 1, the hand of' the opera-tor is understood to be upon the outer end of H. While the parts are in this position, and e is below fw, the water is flowing into the space around G, and thence through p p and o o to the nozzle. If the pressure ot' the hand be withdrawn, the parts react with a rapidityregulatedv by the diameter of' d, or, it' a be used, the combined diameters, the hydrant having no tendency to close faster than the space formed below c can be filled by its feeder. When the closure is complete and the parts are all up, c has passed abovep 19', cutting oi' the How, and chas the wasteway below it, lallowing the water in T to escape through w, and thence along the bore b into the ground.

' When, in the downstroke, the upper line of Vc passes the apex of the ports, a very small How of water begins, and this grows so gradulally as the stroke advances and the wider part Y 'ot' the ports is uncovered, that no jerkI or un.

.equal resistance is felt by the hand. The same y'through d.

Having thus fully explained the construe,

or tube of a hydrant, to actuate the lower parts thereof, all substantially as shown, and

with the objects and for the purposes speciied.v

2. In combination with the hollow rod ot' a wasting-hydrant, the plunger P, with its openings o o and cups c c', and the cylinder O, with its perforations w, p p', and 1", When operatin g conjointly, substantially as described, to let on and shut oft' the water, close the hydrant, and allow the contents of T to Waste.

v3. The regulator R, cupped and channeled, substantiallyvas shown, and attached to the plunger P, to control its reaction, as explained.

4. In combination with plunger P, cylinder C, and regulator R', the auxiliary puncture a, asset forth.

5. The yoke Y, when combined with the bed-piece and Wooden stock of a hydrant, as shown, and for the purpose specified.
